Sphere-9 PAF China Study
Treatment of Paroxysmal Atrial Fibrillation With the Sphere-9™ Catheter and Affera™ Integrated Mapping and Ablation System in China
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2026. aug. 27.
Rövid összefoglaló (regiszter, angolul)
The goal of this clinical trial is to find out if the Sphere-9 Catheter and Affera Integrated Mapping and Ablation System is safe and works to treat recurrent symptomatic paroxysmal atrial fibrillation (PAF) in adults who have not been helped by, cannot tolerate, or cannot take certain medicines for PAF. The main questions it aims to answer are: Is the Sphere-9 Catheter and Affera Integrated Mapping and Ablation System safe for treating PAF? Does the treatment help keep patients free from atrial fibrillation and other abnormal heart rhythms during the 12 months after the procedure? Participants will: Have their heart rhythm assessed before and after the ablation procedure. Have PAF treated using the Sphere-9 Catheter and Affera Integrated Mapping and Ablation System. Have follow-up visits at 3, 6, and 12 months after the procedure.

- Presence of a permanent pacemaker, biventricular pacemaker, , or any type of implantable cardiac defibrillator (with or without biventricular pacing function), , or presence of a loop recorder or insertable cardiac monitor (ICM) that has not reached manufacturer-defined end of service (or equivalent end-of-life state)
- Any cardiac surgery, myocardial infarction, PCI / PTCA or coronary artery stenting which occurred during the 3-month interval preceding the consent date
- Unstable angina
- Severe lung disease, primary pulmonary hypertension, or any lung disease with abnormal blood gases or requiring supplemental oxygen
- Rheumatic heart disease
- Severe thrombocytosis, thrombocytopenia, or any bleeding or clotting disorder
- Active systemic infection or sepsis
- History of thromboembolic event within the past 6 months or evidence of intracardiac thrombus at the time of the procedure

- Amyloid heart disease (cardiac amyloidosis)
Laborértékek
- NYHA Class III or IV congestive heart failure or documented left ventricular ejection fraction (LVEF) less than or equal to 40% measure by acceptable cardiac testing (e.g. TTE), or planned transplant or left ventricular assist device (LVAD)

- Patient with life expectancy that makes it unlikely 12 months of follow-up will be completed
- Body mass index > 40 kg/m2
- Atrial myxoma
- Presence of intramural thrombus, tumor, or other abnormality that precludes vascular access, catheter introduction, or manipulation
- Significant congenital anomaly or medical problem that, in the opinion of the investigator, would preclude enrollment in this study or compliance with follow-up requirements or would impact the scientific soundness of the clinical trial results.
Kiket keres a vizsgálat
- Failure of, intolerance to, or contraindication to at least one Class I-IV AAD for the treatment of PAF, as evidenced by recurrent symptomatic AF. A diagnosis of recurrent symptomatic PAF, which is defined as continuous AF episode lasting longer than 30 seconds but terminates spontaneously or with intervention within 7 days of onset, documented by the following:
- a physician's note indicating at least 2 symptomatic PAF episodes occurring within 6 months prior to enrollment; and
- at least 1 electrocardiographically documented episode within 12 months prior to enrollment
